  • Give an example of an r-selected species
    Mice, insects, frogs etc.
  • A decomposer can be correctly defined as
    an organism that utilises dead organisms for its nutrient requirements by breaking down the organic molecules into inorganic molecules
  • Molecular phylogeny uses which type of data to classify organisms?
    DNA, RNA, or protein sequences
  • List two ecological surveying techniques commonly used in stratified sampling
    Quadrats, transects
  • In the nitrogen cycle, the bacteria that convert ammonia into nitrate can be correctly identified as
    nitrifying bacteria
  • Which interaction occurs when one organism kills and eats another?
    Predation
  • Define Symbiosis
    living arrangements between members of two different species, including mutualism, commensalism, and parasitism.
  • Why is classifying ecosystems important for effective ecosystem management?
    It provides a structured way to identify, compare, and conserve ecosystems
  • Define competition
    Competition occurs when two or more species compete for the same limited resource, such as food, water, or territory
  • What is the main purpose of stratified sampling in ecology?
    To make sure samples cover different habitat zones or gradients
  • Define a microhabitat
    A microhabitat is a small, specific area within a larger habitat that provides unique environmental conditions.
  • Which is the BIGGEST scale out of microhabitat, ecoregion and ecosystem?
    ecoregion
  • Define Predation
    Predation is a biological interaction in which one organism, the predator, kills and eats another organism, its prey.
  • List the seven main taxonomic ranks in the Linnaean classification system from broadest to most specific
    Kingdom, Phylum, Class, Order, Family, Genus, Species
  • Define the term Clade
    a group of organisms with a common ancestor
  • Give an example of an interspecific hybrid that is not fertile
    Mule, Liger, etc.
